hector_quadrotor_model: added cmake_modules dependency
hector_quadrotor_controller: always disconnect handle on deconstruction
hector_quadrotor_controller: make a copy of the root NodeHandle in all controllers

For some reason deconstructing the TwistController resulted in a pure virtual function call without this patch.
